firmly press together (fig. 15). Tighten the table clamp (ee) with
socket wrench (fig. 16).
8. Insert a M8 x 25 screw and D8 washer into the back, left table strip
and securely tighten (fig. 17, 18).
9. Repeat for back right table strip.
MOUNTING DUST SHROUD (FIG. 19, 20)

MOUNTING THE CABLE SUPPORT (FIG. 21, 22)
1. Remove the cross head screw (ff).
2. Mount the cable support (gg) and refit the cross head screw.
3. Remove the cable clamps (hh, ii) located on the arm and reattach
holding the cable in place.
WARNING: Allow for the arm movement in horizontal and
vertical direction.
MOUNTING THE ELECTRONIC CONTROL BOX (FIG. 23)
Wired into the mains cable is the electronic control box (x) containing
the no-volt release switch (w), on three-phase models also including the
braking device and the motor overload protector with automatic reset.
1. Remove the nuts from the screws (jj) protruding out of the rear of
the box (x).
2. Hold the box against the rear of the table frame to the left of the
column base and insert the screws into the corresponding holes.
3. Replace the nuts onto the end of the screws and tighten them.
MOUNTING THE SAW BLADE (FIG. 24–33)
1. Ensure that the arm position is at 0˚ and raise the arm (m) to the
upper postion (fig. 24).
2. Loosen the guard screw (kk) and lift the guard (d) out of the way
(fig. 25).
3. Using the 6 mm hex key inserted into the motor spindle and the
13 mm spanner key on the blade screw (fig. 26), turn the spanner
key clockwise to remove the blade screw (ll) and external flange
(mm).
4. Remove the blade from the spindle and fit the blade in the slot (nn)
of the table fence. The teeth blade MUST NOT come into contact
the spindle (fig. 27, 28).
5. Unlock the head and move the head forward until the blade can
be removed from the slot (nn). Place the new blade (oo) into the
slot (nn) and move the head slowly into the rest (locked) position
assuring that the teeth of the blade does not come into contact
with the spindle (fig. 29–31).
6. Place the new blade onto the internal flange (qq). Place the external
flange on the spindle. Using a 6 mm hex key in the motor spindle
and the 13 mm spanner key on the blade screw, tighten the blade
screw and external flange (fig. 32).
7. Lower the guard so the guard slot is aligned with the guard screw
and tighten the screw (fig. 33).
8. The head is ready for cutting.
WARNING: The teeth of a new blade are very sharp and
can be dangerous.
WARNING: The direction of rotation is indicated by the
arrow on the motor.
WARNING: Make sure that the washer of the arbour nut is
against the outer flange.
CHECKING THAT THE ARM IS PARALLEL TO THE TABLE TOP (FIG. 1, 34)
1. Lower the blade (oo) until it only just touches the fixed table top (e).
2. Release the mitre latch lever (j) and the mitre clamp lever (k).
3. Extend the blade forward past the fence then swing arm so that
the blade skims the table top across its width.
4. Repeat this procedure with the blade in rear position and adjust the
rear bolt if required.
CHECKING THAT THE BLADE IS PERPENDICULAR TO THE TABLE TOP
(FIG. 1, 35–37)
1. Bring the arm (m) back to central position.
2. Place a steel square (rr) against the blade body (fig. 35).
3. If adjustment is required, proceed as follows:
a. Remove the bevel pointer disk (tt) by loosening the two screws
(uu) (fig. 36).
b. Loosen all three hex screws that will be exposed in this way
(fig. 37).
c. Place a hex key in the motor arbour and tap until the blade is flat
against the square.
4. Firmly tighten all fasteners.
WARNING: It is particularly important to tighten the central
hex screw.
5. Replace the bevel pointer disk (tt) aligning the pointer (ss) at 0˚.
CHECKING THAT THE CROSSCUT TRAVEL IS PERPENDICULAR TO THE FENCE
(FIG. 38–42)
1. Extend the blade in front of the fence (fig. 38).
2. Place a square (rr) on a piece of board and against the fence and
just touching the blade as shown.
3. Pull the blade towards you to check that the blade traverses
parallel to the square.
4. If adjustment is required, proceed as follows:
a. With the mitre latch lever (j) engaged in 0° position, release the
mitre clamp lever (k) as shown in figure 39.
b. Loosen the locknuts (v v) on each side of the arm (m), shown in

figure 40.

5. To adjust the arm (m) to the left, loosen the stud (ww) on the right-
hand side of the arm and tighten the opposite stud (fig. 41).
6. To adjust the arm (m) to the right, loosen the stud (ww) on the left-
hand side of the arm and tighten the opposite stud.
7. Proceed in small steps and check the adjustment after each step
with the levers (j, k) engaged.
WARNING: Do not overtighten the studs.
